The geochemical characteristics of metabasites with a pseudo-pillow structure from Ganghe, Dabie Orogen, China

► Four metabasite lenses with pseudo-pillow structures are geochemically studied. ► Their protoliths were formed during the Neoproterozoic. ► The mafic protoliths experienced meteoric-hydrothermal alternation. ► The protoliths source were contaminated by old lower crustal materials. ► The metabasites have the similar characteristics as NHY Neoproterozoic basites.
